Question

2. Evaluate:

Suppose you want to buy something for $60, and you have $15 saved up so far. Then your grandmother calls and says she will chip in for your purchase. She doesn’t tell you the amount of money she will give you yet, so you just consider it x dollars.

and need the answer to this

grandma's bonus =

hence, $45 + x = $60

Collect like terms

60 - 45 =

X = $15
